This invention relates'toA closures for containers of materials whichare to be dispensed therefrom and more particularly to Closures or capsof containers' for medicinal and pro- 5 prietary preparations such astooth paste,

shavingcreams and the like, Vand it will be understood 'from thedisclosure that the in,-l vention is susceptible of a Wide range of useswhich need not be specified.V i

Itis an object of this invention to provide a closurecapable of beingattached to the neck of, a container such as collapsible tubes in whichsuch commodities are usually distributed andpreferably'fthe Vclosure iscoul' structed by using rubber, as rubber having certain characteristicsis sufficiently resistant to deterioration and Wearas to possess thenecessary endurance incident to its use.

Itis a further object of'this inventionk to provideA closures ofthecharacterfindicated which can berexpeditiously applied `to the necksof closures 'of the character indicated andthel said device will beoperable to prevent leakage of the contents of the container When it isclosed, although parts of the closure may be manipulated to provide forthe discharge of the contents of the container and then readjusted tothe aforesaid position to prevent such discharge and furthermore theinvention has for its object the provision of means whereby materialwhich is in the ori-` fices or discharge channels will be forced backinto the container and the exit opening so sealed as to prevent furtherdischarge until the device is again manipulated.

It is furthermore an object of the invention to provide novel means toguard against the escape of the material issuing from the 40 containerexcept through the channels prepared for thedispensing of the contentsof the container.

With the foregoing and other objects in View, the invention consists inthe details vof construction, and in the arrangement and combination ofparts to be hereinafter more fully set forth and claimed.

lIn describing the invention in detail, ref` erence will be had to theaccompanying draw` ing forming part of this application Wherein likecharacters denote corresponding parts in the several views, and linwhich; i Figure l illustrates a-view `in elevation of Aa fragment of acontainer showingthe closure, partly in section, applied thereto;

In the present embodiment of `the invenonthe j C tion, a'closure A isapplied to a ycontainer VB which isillustrated as of the collapsibletube type;` `A coneelike plug C' is` preferably formed integral with ahorizontalpartitionm or Wall-0 having discharge apertures D. l AspinEextendsthrou'gh the annularneck e of the container 4anditprojectsbeyond the outer surface of the neck and enters a slot F ,Yformed in the skirt or tubular portion fp of the closure A, it'b'eingshown that the closure A has an aperturelG into which the cone-like plugprojects. l

Theclosure has an annular channel H into which the upperA end of theneck projects, it being shown that the said upper end of the vneck litssnugly in theannular channel and the relation of parts is such, thatmaterial issuing from the container can not pass be. tween the Wall ofthe annular channel 'and 85 the sides of the upper .end of thefneckwhich Y project into the saidchannel. It is'yalso shown that thedischarge opening Gr in the closure has walls g'which diverge towardthe.V

bottom so that the discharge openingis larger 901' at the lower end thanitis at the upper end. It is also shown that the cone-likeplugG Y istapered and it is the purpose of the invenj tor that the contactingsurfaces of the closure and plug'shall be such vthat it'will resultvin Ya` tight joint'betwe'en them Whenfthe cap isl closed so as to preventdischarge of thecon-v 7 fr tents'of the container.` Furthermorathe caphas an annularV shoulder h-,and the relation of'` parts ispreferablysuch that when they I0@ perspective 'viewcf 60 l l 1 Ye0[moved to eifect the seating action to which lcap is'closed in themanner ljust stated,the
